With AMC's 'Breaking Bad' in our rear view mirror, and 'Mad Men' to follow sooner than we'd like, April 6 will see Revolutionary War drama 'Turn' introducing us to America's first spy ring with its series premiere. The latest AMC period piece has some rich history behind it, so take a minute to meet Daniel Henshall's pivotal courier character Caleb, courtesy of an exclusive preview from AMC's 'Turn'!

Based on Alexander Rose’s book, ‘Washington’s Spies,’ written by showrunner Craig Silverstein (‘Nikita’) and executive produced by ‘Bones’’ Barry Josephson, ‘Turn’ is set in 1778 and follows Abe Woodhull (Jamie Bell) as he bands together with a group of friends to form The Culper Ring, an unlikely group of spies who turn the tide in America’s fight for independence.

We've seen the first few episodes of AMC's 'Turn,' and don't mind telling you it's more than worth checking out, so take a look at our exclusive preview for the Revolutionary War drama above, and tune in Sunday, April 6 at 9:00 P.M. for the premiere!
